Sleepy Lagoon is a 1943 American musical comedy film directed by Joseph Santley and featuring comedian Judy Canova and singer Dennis Day. The film was written by Prescott Chaplin, while Frank Gill, Jr. and George Carleton Brown wrote the screenplay. It was Canova's final feature for the Republic studios until 1951.

While closely coincident in time, the movie was entirely unrelated to the Sleepy Lagoon murder which led to the Zoot Suit Riots, nor to the song which lent its name to that incident.
